**Descriptions:**  
The LM5008SD is a step-down (buck) switching regulator designed for high-voltage applications. It integrates a high-side N-channel MOSFET and features a fixed-frequency current-mode control for stable operation.  

**Features:**  
- Wide input voltage range (6V to 75V)  
- Integrated high-side MOSFET  
- Adjustable output voltage  
- Adjustable switching frequency  
- Thermal shutdown protection  
- Under-voltage lockout (UVLO)  
- Current-mode control for improved transient response  
- Low shutdown current (<1µA)  

This regulator is suitable for industrial, automotive, and power supply applications requiring high efficiency and compact design.
